In addition to Xbox Live achievements, the Windows 8.1 version includes some new cars, including the Tramontana XTR and Arrinera Hussarya, along with a new location, three new winter-themed tracks and more. It also shows that Gameloft continues to be supportive of Microsoft's Xbox Live system by updating more games to include those features that are highly requested by Windows gaming fans.

One question, isn't Xbox games certification is very troublesome for developers to get pass? Why are there so many gameloft's game updated with Xbox live support? Microsoft changed their policy for Xbox windows phone games?

Thank you!!! I'm glad someone agrees here. I played it the second it came out, because I loved the first game. However, you need to quit your day job to be able to get cars with out in app purchasing. The 7th game did it perfectly.
